Oswego County's three nuclear energy facilities will soon begin a project to replace the county's aging public warning system.

Constellation Energy Nuclear Group, which owns the two Nine Mile Point nuclear plants, and Entergy, which owns the James A. Fitzpatrick Nuclear Power Plant, will invest more than $1.5 million to replace the existing sirens in the ten mile radius around the plants.

Jill Lyon, with Constellation, says the sirens are currently used by several groups.

For the second time in less than a week, the Nine Mile Point Unit 2 nuclear power plant in Oswego County experienced an automatic shutdown, due to a problem at the plant.

The shutdown happened around 4:30 p.m. Monday. According to a spokesperson from Constellation Energy, which owns the plant, a worker "inadvertently contacted a highly sensitive plant component." As a result, safety systems shut down the plant automatically.
